Referring now in detail to these drawings the body of the stove consists of a rectangular casing, preferably formed of sheet metal, and of which the base appears at 20, the sides at 21 and 22, the top'at 23, and the 'back at 24E, referring particularly to Figs.

1, 2 and 3 of the drawings. a

According to my present construction, the sides 21 and 22,as clearly seen in Fig. 3 are integral with the bottom 20, being` bent upwardly from the sides of Athe bottom at right angles thereto, with their top edges having inturned flanges 25, providing for he connection ofthe top 23, secured to said flanges by suitable means, preferably electrical spot welding. It Vis vappa-rent that the separate top permits of the useof a top plate of heavier than the remaining portions, thus adding to its durability and consequently its life in use. Before the strip of which the base and sides are formed is bent in shape, its longitudinal side edges are preferably bent inwardly and flattened thereupon to form 'reverting flanges 26, as seen in Fig. 6, thus reinforcing the forward and 'rear edges of the base 2O and the sides 21 and 22.

The back plate 24E is preferably formed of a single piece of sheet metal, having flanges telescoped within the rear of the casing, the flanges 27 thereof appearing in F ig. 6 and being secured to the inner surfaces of the casing at the rear thereof, preferably by electrical spot welding, so that the outer surface of the back plate is flush with the rearredges of the top, bottom and side walls.

fi division plate 23 is secured longitudinally Within the body between its sides 2l and 22 and parallel therewith, dividing the space within the casing into two compartments, namely, a lire box 29 and `an oven space 30, the said division plate fitting closely within the casing and havingtherearound laterally extended flanges 3l as seen in Figs. 3 and 8, apertured to correspond with apertures 'in the walls of the casing adjacent to' which the flanges 31 extend, for the purpose of receiving connecting bolts 32, securely fasteningk the vpartition plate in position. As seen in the detail Fig. 8 of the division plate 2S, this plate is provided near its upper edge with a plurality of openings 33, providing for the passage of the products of combustion from the lire bo); 29 to the oven space 30l As also shown inthe same figure, the partition plate 2S' is provided on the fire boX side thereof a plurality of ver-v tical angle-bars 3ft, forming strengthening ribs to stiffen the plate and space the fuel therefrom. v l

The'front plate of the casing, as seen in Figs. l, el and 6,' and in the detail Fig. '7 is formed of a single sheet with flanges 36 therearound to telescope within the front A portion of the casing, the flanges and consequently thel front plate being properly secured to the forward portion of the casing walls preferably by electrical spot welding,

substantially the same as the back lplate 24.

lThis front plate 35, as seen in Fig. 7, is pro- Y i 40, al, and 42, of which the doors i0 and ill,

i' 'i vel a r ire .i x oaenino's are covein theofi nlf lo g hinged to the front plate 43 at their outer edges as will be hereinafter more fully described. The door 4t2 controlling thefilraft openings isv slidable laterally beneath the door ell; Y Y

T he opening `37 of thefront plate 35 is surrounded by a marginal depressed portion la standing at a right angle, which servesto stiffen the front plate 35 and to receive and seat from a single sheet of metal bent into rectangular form, the ends of which metal sheet are lapped the entire length and width of one side wall of the oven f6 nearest the partition plate 28, as seen at 47, the two portions so lapping being preferably connected by electrical spot welding, thus giving a double thickness Vfor protection and strength at the `point only to hold said bolt rigidly in place with regard to the casing, but also-serves as aV spacing means to permit the passage of heat around the end of the oven. This bolt 49 is provided .on its inner end with a nut 5l which holds the inner end of the oven securely in place relative to the casing, and thus drawing and seating its flanges l5 snugly within the marginal depression all s rrounding the .opening 37 of the front plate 35, as before mentioned. To remove the oven from the casing with ease for repairs or cleaning',

it will be sufficient to unscrew the mit 5l and pull out the oven body to the front. "For easy replacement the oven body is .guided exactly to its proper alinement and position by sliding movementv along the lower face or flange of the brace or damper plate Each of the front doors ll0 and il is retained in thenclosed position by means of hinges made up in part of the doors, and latch arrangement comprising a bar 5l secured fast to the door and having an inwardly projecting arm 52notched as at 52a, which bar is rigidly secured tothe door and also serves as a holder for thering Sel, which serves as a convenient handleto the door Vwhen said ring is swung out, but the said ring may be swung close in against the face of the door when desired, asshown in Figs. l and l5. Y Y

y This notched arm has its lower inclined surface 52h slightly lbelow the lower wall of the slot 53,-cut in the front plate 35, so

,that when theV door is swnngto the closed position the inclinedrface will' ride up on the Ylower wall of said slot, causing-the J resiliency of the metal parts to snap the latch into engagement, and the door will be held firmly lclosed against accidentalV displacement.` ln'order to open ,the door, it Awill be Vsimply necessary to lift on the bar 5l, disengaging the latch from engagement with the' lower Ywall Vof the slot This lifting can be conveniently done by inserting a lifting ,tool through therring 5e.

7lhns it will be seen that this latch automatically operateswhen the :door is swung quickly to, andthe door may be opened by simply lifting up on the latch and swinging it outward.

The latch, be it noted, is rigidly attached to, and is to. all intents and purposes an integral part of the door.-

lVhen the stove is inthe knock-down po- Sition, as shown in Fig. 1, the bar 80 covers the rings 54, and not only prevents rattling, but also prevents the rings from swinging outward. Moreover, this bar Serves as an auxiliary latch to prevent the doors from opening.Y

lVithin the casing a combined brace and cut-off plate is provided, shown most clearly in Figs. 3 and 6, which is'shown as Zshaped in cross section, and is secured to the underside of the top plate,`terniinating at a. distance from the front wall of the casing, so as to provide a passage 56 forthe hot products of combustion, as shown in Fig. 6. This cut-off platejnot only serves asV a baffle plate, but also serves as a guide and brace at the top of the oven. 'The lower and unattached fia-nge of this plate55 tends to be expanded by ,the heat to forni a tight joint with the top of the oven, except at the open space 56.

The top plate 23 is lprovided with an open-` ing 58 for the lower end of the stove pipe, and around this .opening I provide a plurality of upwardly-opening h00ks59, preferably'three" in number, which are spaced around the opening 58 andhave. their inner ends 61 secured to the top plate 23, as shown most clearly in Figs. 1, 12 and 13. These hooks are used to lock'the lower end of the stove pipe in place,.by 'pressing outwardly against the lowe 1, inner wall of the pipe 60.

The opening 58 in thetop plate 23 is provided with a shoulder 62 (see Fig. 12) to engage, in connection with one of thehooks 59, the interlocking folds63 of the lower end of the stove pipe, and hold same in locked position when the Stove mounted in place on thestove.-

rEhe stove pipe 60, open, at one side, as shown in Fig. 14, yis provided with 'oppositely-disposedY engaging flanges 63, which flanges tend to hook-into each other owing to the resiliency of the metal when it is desired to set up the pipe, as shown in Fig. 11, but ywhich* permitthe pipe to be rolled in a compact mass and stored within this portpipe is Y able stove. Y

' in such event, the pipe 1s stowed in theV furnace compartment of the stove. It will be seen that when the lower end of the Stove pipe is placed situ, as shown in Figs. 1 and 13, these hooks will serve to keep the lower part of the stove pipe distendcd, and will lock the flanges in the 'engaging position against inward pressure from any cause.

As shown in Eiglfi, the upper end of the stove pipe is cut away at the upper portion .of one edge, as at 64, and has the adjacent `enga-ges the recess formed by the notch 64,

and thus a lock is provided at the upper end of the pipe for preventing the said pipe from being compressed or unlocked at its upper end; the one piece of pipe being sufficient to cause the necessary draft for this portable stove.-

As seen in Figs. 4 and 16 a double warming shelf is provided, comprising the upper and lower plates 66 and 67 connected together by brackets 68, in spaced. relation. These brackets are preferably formed of a single metal'bar lapped over, as at 68, and having the free ends 69 serving as hooks to engage/the eyes 70 formed by staples secured to the casing, as shown most clearly in Figs. 2 and 4.

The plates 66 and 67 are preferably detachably secured to the brackets as by means of suitable bolts so that the plates and the brackets may be knocked down and con- 'Y veniently stored within the stove in transort. P The inner edge of the frame constituted bythe plates 66 and 67 and the brackets 68 rests on the bend 78aL of the supporting legs, thus supporting the warming shelves as will be hereinafter more fully described.

The water tank 71, see Figs. 4 and 17, preferably rectangular in cross section, is provided. with a cover 72 and engaging notches 73 adapted to slip over and engage thebolts 74 (see Fig. 18), by means of which the tank is connected to the casing of the stove. The inner bottom edge of this tank' is supported upon the bend 7 8b of the legs 78, as shown in Fig. 4, as will be hereinafter more fully described.

A pair of supporting members 75 is pivotally attached to the bottom of the stove casing a short distance from and parallel with the front and back of the 'stove by suitable means, preferably clips 76, the supporting members Ybeing Substantially quadrangular in shape' and being of such di men'sions that, when foldedV up around the casing, as in Figs. 1, 2, and 3, they will snugly fit the same and vforni an effective protection therefor.

The members 7 just nientionedare each preferably made of an integral piece of metal circular in cross section, the top and .bottom members, 7 5a and 75",thereof being identical, Veach with a central section which issubstantially straight and with inclined end portions 77 which lead -to the sides formed of straight and inclined portions 78 and 79, thetop and'rbottom melubers just i'nentio-ned being in parallel horizontal ula-nes but `occupying different vertical lli) :planes due to the fact that the Vportions 7 9 vof the side are lbent at angles as seen with respect to the portions 7 8. This structure is ysuch thatthe frames when folded will snugly encompass the ends of the stove casing as seen in Fig. 1, with the major'portion `ofthe sides of such frames extending alongV the corners of the casing to afford maximum protection and as seen in Figs. 1 and 3, the reverse position of the obtuse angle of theV portions 79 covers and protects the staples 70, and the heads of bolts 74. It will be noted that the bends 78a and 78b of the supporting members serve to support the vshelf Yframe on one side, and the. water .tank on the other, respectively, thus taking the weight ofll the fastening means shown near the topV of the shelf frame and the water t-ank, respectively.

Vith the supporting members 75 in the position. as sho-wn in Figs. 1 and 2, horizontal bars 80 are engaged with the sides lof* the frames to extend across the front and rear of the stove casing, the front bar covering the two doors 40 and 41, soas to protect saine and rings 54 and keep the latter closed during transportation and sto-r-VV Y may be placed.

vrllransverse latch bars 82 are pivotally attached to thesides of the supporting members 75 to extend along the sides 21 and 22 Y of the casing in folded position, as shown in Fig. 1, having bent or recurved ends 85 'to engage the oppositesupporting members,

and having offset portions 83 intermediate their ends to 'form liaiidholds, by which the entire 'structure in theV folded position, as shown in'Fig. 1, may be raised and transported from place to place. The latch bars '82 are 'also provided intermediate their ends with bent clamping portions 84 for engagenient with one of the supportingframes when the'latter Vare turned downwardly inV operative' position, inasmuch as the supporting frames in'tliis position are closer toge'the'r than they are in their folded position around the casing, as shown iii Fig. V1, so

that the latch bars may, in the erected position, effectively prevent spreading and rocking movement of the supporting 'frames The hooks 85, at the free ends of the latch I bars 85, project outwardly when the stove lis shown set up in Fig. 5, and serve as convenient arms on which'to hang the various articles used in connection with the operation of the stove.

4 In' operation, in dismantling the stove from vits operative position, as shown in Fig. 4, the `rlatch bars 82 are disengaged from tlie opposite supporting Vframe' 75 after the warming` shelf .has been ldisinounted. and packed with the dufiie or cooking and 'Seiyice out-fit in the tank 71, and the :latter placed withinV the .oven compartment, and the pipe and other necessary utensils are placed in the fire box compartment and the doors closed, the supporting frames are then folded up aroundv the casing to the position shown in Fig. 1 and the latch bars 82 again attached, this time Vat their recurved .tail as and for the purpose set forth, effect-V ing considerable economy i in Yconstruction and increased efficieiicy'in cooking, baking, and heating'qualities. .The removable division plate and also the separate-stove top before described provide .means whereby quick and effective repair or replacement of those parts of the stove which suffer most from 'the heat of the fire, may be made, while the demountable,- double warming 'shelf' and the fluid tankadd materially to the range of useV ofthe stove and to its effectiveness vinfuse and the alinement and easy removal and insertion of the oven provides for cleaning the oven-space at all times, as well 'as for repairs to the division plate. It is furtliei'to be seen that the folding supporting members, in addition to their function as supports in the use of the stove, effectively protect the latter when folded -thereabout and their connections provide for readily carrying thestove bv hand,

as well as a'warming vrackbeneath the stove for bains and vtheir contents, as before described. ltis obviousY alsoV that the detachable and 'demountable collar or pipe 60 is an effective part for this portable .stove which, Y in the folded position of the stove, may be readily removed leaving top plate 23 clear and rolled to occupy a minimum storage space and which'collar or pipe, before stated, is itself of sufficient lengthv to complete the desired draught function of this stove.
